The model requires as input the maximum and minimum daily values of air temperature, wind speed, relative humidity and cloud cover, the timing of the maxima and minima relative to dawn or solar noon, soil properties (conductivity, specific heat, density, solar reflectivity, emissivity) as well as the roughness height, slope and aspect.
Note was taken of the slope height, slope length, slope gradient, lithology, and dip direction of slope, the thickness and slope of the sliding surface.
The variables are the lithology and formation structure, slope height, slope angle, and earthquake and rainfall parameters.
Fig. 5 Thematic map of the slope angle (2) Slope height Slope height plays an important role in landslide occurrence, especially in loess areas.
Combining simultaneously the effects of slope height, slope angle, and groundwater level presented just one optimization point (Fig. 15) which is different from the two presented by the combined effects of slope angle and height only in Fig. 14.
In the 1970s, researchers explored describing anomalous water waves with a differential equation called the non-linear Schroedinger equation that accounts for only the height, slope, and curvature of the evolving waves.
According to the mechanism analyses of the landslides in the loess area, six environmental factors were selected to evaluate landslide occurrence, such as slope height, slope angle, aspect, shape of slope, distance to rivers, and human activities.
Seven control factors, including internal frictional angle, cohesion force, slope height, slope angle, surface gradients, peak acceleration, and distance to fault were selected for analysis of multi-level objective decomposition.
In this article, we introduce the catastrophe progression method to evaluate the seismic stability of embankment, by selecting internal frictional angle, cohesion force, slope height, slope angle, surface gradient, peak acceleration, and distance to fault as evaluation indices.
It was also concluded that increase in strength parameters (cohesion and angle of internal friction) have positive influence on the stability of the dump slopes while increase in slope height, slope angle and groundwater level have damaging and destructive influences on such slopes.
